Abstract：
This study aimed to investigate the association between hepatic VNN1 expression and carcass traits in Mahuang chickens as well as to identify polymorphisms in the upstream and downstream regions of VNN1 that could potentially be associated with these carcass traits. The study revealed that VNN1 expression levels in liver correlated with various carcass traits such as dressed weight, eviscerated weight, and abdominal fat weight. A total of 39 polymorphic sites were identified, among which 23 were found to be associated with 15 different carcass traits. These polymorphic sites were organized into three distinct haplotype blocks, with BLOCK2 and BLOCK3 being associated with various eviscerated weight percentages, thigh weight, breast muscle weight, wing weight, and other traits. The study underscores the significant role of VNN1 in influencing the carcass traits of Mahuang chickens and sheds light on the genetic foundations of these traits. The findings provide valuable insights that could inform breeding strategies aimed at optimizing traits relevant to market demands and slaughtering efficiency.
摘要：
本研究旨在研究马黄鸡肝脏VNN1表达与car体性状之间的关联，并鉴定可能与这些car体性状相关的VNN1上游和下游区域的多态性。研究表明，肝脏中的VNN1表达水平与各种car体性状相关，例如穿衣体重，内脏重量，和腹部脂肪的重量。共鉴定出39个多态位点,其中23个与15个不同的car体性状相关。这些多态性位点被组织成三个不同的单倍型区块，BLOCK2和BLOCK3与各种内脏重量百分比相关，大腿重量,乳房肌肉重量，机翼重量,和其他特征。该研究强调了VNN1在影响麻黄鸡car体性状中的重要作用，并阐明了这些性状的遗传基础。这些发现提供了有价值的见解，可以为旨在优化与市场需求和屠宰效率相关的性状的育种策略提供信息。
